A support for a steering wheel of an agricultural or construction vehicle to improve working conditions of operators inside cabins and, also, to simplify production lines of the vehicle. A steering wheel support is formed by first and second articulated elements which are connected together and fastened on an installation base, and the first articulated element is pivoted on the installation base, while the second articulated element is connected at an opposite end of the first articulated element through a connector element, and a free end of the second articulated element further sustains a framework for installing a steering box with its respective steering wheel.

A tractor in which a lift valve of a hydraulic system for lifting up/down a work machine is mechanically coupled to a lift lever, and conditions for an engine startup are set as follows: a reverser lever is at a neutral position thereof; a PTO (power take-off) clutch is disengaged; a seat switch is ON; and the lift lever is at a lowermost position thereof. A switch driving unit is provided on a side face of the lift lever so that the side face is orthogonal to a turning direction of the lift lever; a switch is provided so as to be opposed to the switch driving unit when the lift lever is turned to be at the lowermost position; and the lift lever at the lowermost position is detected by the switch.

A computer implemented vehicle control method may include obtaining a sensed input from an operator remote from a vehicle, recognizing and associating the sensed input with a vehicle action and outputting control signals to the vehicle to cause the vehicle to carry out the vehicle action.

A vehicle may include a movable roof, a sensor supported by the roof, and an actuator for selectively raising and lowering the roof.

A tractor hydraulic adaptor, system and process to hydraulically power a hydraulic attachment on a tractor is disclosed. The hydraulic adapter includes a hydraulic intensifier powered by a tractor's power take off shaft to drive a hydraulic attachment coupled to a tractor's front-end loader. The hydraulic intensifier draws at a low-pressure hydraulic fluid and feeds the hydraulic fluid at a higher pressure to the hydraulic attachment.

A sprayer vehicle includes a chassis having a longitudinal axis and supported by a plurality of wheels, a boom carried by the chassis, and a pivoting mechanism. The boom has a first boom extension and a second boom extension, each carrying a plurality of nozzles configured to discharge material. The pivoting mechanism is configured to co-linearly orient the first boom extension at an acute angle relative to the longitudinal axis of the chassis and the second boom extension at an obtuse angle relative to the longitudinal axis of the chassis. Other sprayer vehicles are configured to discharge material while the wheels of the sprayer are oriented at an acute angle relative to a longitudinal axis of the chassis. Control systems and methods are also disclosed.

An agricultural machine includes a vehicle body including a front wheel and a rear wheel, a hood at a front portion of the vehicle body, a protector provided to the vehicle body to protect an operator seat, and an obstacle detector to detect an obstacle, the obstacle detector being located in front of the protector outwardly in a width direction of the hood.

A fender support structure includes a base member that rotates in accordance with a steering of a front wheel, a cover member that is relatively rotatable with respect to the base member and that supports a front wheel fender covering the front wheel, a holding mechanism that is accommodated in the base member and the cover member and that generates a holding force to hold a relative rotational position of the cover member relative to the base member at a predetermined initial position, and a regulating mechanism that regulates a rotation of the cover member in accordance with a steering of the front wheel against the holding force when a steering angle of the front wheel becomes a predetermined value or more in a left direction and a right direction.
